install/sd-vconsole: fix console font search to include required fonts
need to look for font files with extensions ".psfu", ".psf", ".cp" and ".fnt" font files can be compresed with gzip or bzip2 and some font files aren't fonts itself but just list of partial font names those start with header "# combine partial fonts"
Fixed patch from FS#45444.
This can be tested with e.g. FONT=iso01.08
in /etc/vconsole.conf
